Classroom teachers are already loving this resource!

—--“This curriculum provides fun & interactive activities for my students. It also includes differentiated support for my small groups. I love all of the opportunities for learning!”  - Melanie

—--“I am going to use this as a supplement along with my district’s curriculum. Our current curriculum spirals, but doesn’t give nearly enough lessons and activities for my students to gain a true understanding of a concept or skill. With this program, I will not only have additional activities for my students to use, but also lessons, hands-on and collaborative activities, and differentiation tasks for those that need intervention or extension on the skill. This is just what I needed!”- Taylor

I can’t wait to hear how this addition & subtraction unit helps your student achieve success with math fact fluency in a positive, encouraging, teacher-friendly way! Send me a message after you download and let me know how it’s going. Happy teaching!

    This resource is amazing! I cannot say enough good things about it. Easy to use and everything is planned out. My students love all the activities and such a wide variety of activities too!

  2. Raquel C.

    This unit was excellent to use to make these standards more engaging. I always turn to these units to supplement my district curriculum and I appreciate how organized and easy-to-follow they are.

  3. Reading Roads LLC

    I attribute my class’s progressing math skills (especially math fact fluency) to this seller’s resources. Every resource is engaging and appropriate. Honestly, you can’t go wrong.

  4. WiseINfirst

    “This is more fun than our math book!” This resource is a game changer… especially when you need to supplement for a math curriculum that isn’t student (or teacher) friendly!

  5. Nicole D.

    I love this, my class loves this. The science connection is fantastic and the movement activities that are incorporated into each lesson are fun and engaging!

  6. Lewis’s Little Learners

    This made teaching math so much fun! The kids were engaged and loved the variety of activities. Since I’m using this resource with first graders, I spread the lessons out over two days each, and it worked great! Fun practice pages and the review sheets were SO helpful.

  7. Candace B.

    I love the variety of activities. I used it to supplement in my intervention group and it was nice to have something different but focusing on the same skills being taught in the classroom.

  8. Angela D.

    This product is amazing. My students loved using this product with partners and during small group. The activities are interesting, and easy to understand. I am extremely satisfied with this purchase. Thanks for sharing!

  9. Opal A.

    I’m a homeschool mom to my daughter. She is 8, has autism, and is obsessed with animals. She may also have dyslexia and dysgraphia so she struggles with holding numbers in her head while doing addition and subtraction (and now we’ve started multiplication and is getting confused with addition 🙁 . I got this unit because I knew she would be all for it and I’m hoping it helps having the extra practice with animals 🙂 I love the strategy posters and we put those up on the wall right away and while she was doing her math she went over and used them and I asked her if they helped and she said yes! I have never seen a unit of any kind (math or LA) that is based around animals. So thank you!!

  10. Adventuring into Education

    This is the best resource ever! I’m going to be leaving my school in December, and I am trying to be completely prepped and done with my lesson plans and printouts ASAP so I can focus on other things. This resource saved my life in math! I have SUCH a hard time planning math, and this was perfect to just print, a little prep, and be done! The slides are interactive and engaging, and my students love seeing the different habitats and environments.
